Abstract
The present invention relates to a flow discharge device () for discharging a flow of gas (F) from a first gaseous fluid (A) into a second gaseous fluid (B) which is of a lower pressure than the first gaseous fluid. The discharge device comprises a valve () disposed between the first and second gaseous fluids and arranged to regulate the discharge flow (F) and a swirler means () disposed between the valve () and the second gaseous fluid. The swirler means () comprises a plurality of radially extending circumferentially spaced vanes (). In use the swirler means () swirls the discharge flow (F). This acts to reduce the energy, and therefore the pressure of the discharge flow. This results in quieter operation.
